Used as an inhibitor of proteins involved in circadian rhythm control, specifically targeting the CLOCK-BMAL1 complex, which plays a role in balancing genes that regulate various cellular activities according to the time of day. It is employed in research on circadian biology. Disruptions in circadian rhythms are associated with various diseases, such as depression, obesity, diabetes, and sleep disorders. Therefore, BML-260 has potential as a research tool to understand the mechanisms of circadian-related diseases and may lead to the development of future treatment approaches.
